[GitHub] [shardingsphere] sandynz commented on pull request #12267: Drop PostgreSQL replication slot when scaling task finished

URL: https://github.com/apache/shardingsphere/pull/12267#issuecomment-914260198


   Why we change it:
   
   1, From openGauss testing response, execute `SELECT * FROM pg_create_logical_replication_slot('slot'_name, 'test_decoding');` repeatedly will cause exception, and error code is different as PostgreSQL, so exception thrown will cause scaling task broken.
   
   We'll check whether slot exists before create it, and drop slot when scaling task finished.
   
   2, Keep slot after task finished, it will cost system resources unnecessaryly.
